About This Site

This site unofficially tracks scores for local area high schools. Prior to 2009-2010, I tracked all of Oakland County. Since then, I've focused on the Oakland Activities Association (OAA). Presently, I track baseball, and soccer for both boys and girls.

My primary rating is David Wilson's performance rating system. As a secondary rating system, I use the late David Rothman's FACT system.

Rating Systems

Wilson Performance Ratings

A team's rating is the weighted average of its opponents' ratings plus 100 for a win or minus 100 for a loss. Wins that lower a rating or losses that raise a rating count one-twentieth (5%) of the normal value. Final margins of victory are ignored. Post-season games count double. This system is in the public domain and it may be freely used and published.

FACT Ratings

FACT considers the margin of victory, albeit with diminishing returns. Each additional point, goal, etc. adds less value than the previous one. The intent is to deter running up the score for rating's sake. Teams are mapped to points on a logistic curve based on who they have defeated and lost to and based on the final scores. FACT disregards all forfeits and weights all games equally. This system is in the public doman as well.

Disclaimer

I provide all scores and information on an as-is basis. Not every score gets reported to a media or social site. Use of this data is for informational and entertainment purposes only, and at your own risk.
